Etymology: Algansea: Latin, algensis, -e = somebody that eats algae; cited by Plinius (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; pelagic; depth range - m (Ref. ), usually - m (Ref. ). Subtropical; 0°C -

Maturity: Lm ?  range ? - ? cm
Max length : 10.1 cm SL male/unsexed; (Ref. 82373)
Morphology | Morphometrics
24-25 transverse scales (rarely 26); 14 upper
row scales (occasionally 13 or 15); 14-19 pores in the infraorbital head sensory canal (usually 15-16). Body is divided dorsoventrally into 4 pigmentation zones as follows: a dark dorsal region; a light band equal to or greater than the width of the pupil; a prominent dark lateral stripe along body, considerably narrower at the anterior region just before the opercular opening; and a silver ventral region. Black spot at the base of caudal fi n set off from lateral stripe by a constriction of the pigment band, the spot extending out onto median caudal interradial membranes. Lateral line pigmented, edged by high concentrations of melanophores around scale pores (Ref. 82373).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.9 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (28 of 100) .
